Technical Field

[0001] The utility model relates to the technical field of concrete admixture preparation, in particular to an admixture raw material premixing device. Background Art

[0002] Concrete admixtures refer to substances added during the mixing process to improve the performance of concrete. Commonly used concrete admixtures include water reducers, retarders, quick-setting agents, expansive agents, antifreeze agents and colorants. Their functions are different, and different types of admixtures can be added according to the performance requirements of concrete.

[0003] In the current preparation process of some admixtures, in order to ensure the processing effect, the raw materials need to be mixed together and pre-mixed before being passed into the processing equipment to form a raw material mixture to improve the processing effect and finished product quality. However, the current pre-mixing work is mostly carried out independently of the processing equipment, and the mixture is then passed into the processing equipment after completion. There is still room for improvement in work efficiency. Utility Model Content

[0037] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0038] See also Figures 1 to 5In an embodiment of the present invention, a device for premixing raw materials of an admixture includes a feed hopper 1, a sealing cover 2, and a pre-stirring rod 3. The feed hopper 1 includes a hopper body 101; the sealing cover 2 is relatively fixedly clamped at the opening on the hopper body 101, the sealing cover 2 includes a cover body 201, a bottom support 203 is fixedly installed at the bottom of the cover body 201, and a pre-mixing chamber 204 is opened inside the cover body 201 and the bottom support 203; the pre-stirring rod 3 includes a motor 301, the motor 301 is relatively fixedly installed on the upper surface of the sealing cover 2, a connecting shaft 302 is fixedly installed at the output end of the motor 301, and a plurality of stirring rods 303 are fixedly installed at equal angles on the side surface of the upper half of the connecting shaft 302. The stirring rod 303 is rotatably installed inside the pre-mixing chamber 204, and a stirring blade 304 is fixedly installed on the side surface of the stirring rod 303.

[0039] Specifically, the various raw materials of the admixture are introduced into the premixing chamber 204, and at the same time, the motor 301 is started to drive the various stirring rods 303 to rotate, and then the various raw materials in the premixing chamber 204 are stirred and mixed by the stirring blades 304. The premixing work is carried out while the hopper body 101 and the cover body 201 are continuously guided and conveyed to ensure that the various raw materials are premixed and in a state of continuous conveying and flow, so as to improve work efficiency.

[0040] Example 1

[0041] like Figure 1 As shown, in this embodiment, the cover 2 also includes a sealing gasket 202, a flow port 206, a shut-off seat 205, a drainage port 207, a raw material inlet channel 208 and a feed interface 209. The sealing gasket 202 is fixedly sleeved on the lower edge of the side surface of the cover body 201, and the cover body 201 and the upper opening of the hopper body 101 are relatively fixed and clamped by bolts; the flow port 206 is inserted and opened at the bottom of the base 203; the shut-off seat 205 is fixedly installed at the upper opening of the flow port 206; the drainage port 207 is fixedly installed at the lower opening of the flow port 206; there are several raw material inlet channels 208, and several raw material inlet channels 208 are opened on the upper edge of the side cavity wall of the premixing chamber 204; the feed interface 209 is fixedly installed at the upper opening of the raw material inlet channel 208.

[0042] In this embodiment, the feed interface 209 is connected to the supply pipeline of each raw material, and the raw materials are continuously fed into the pre-mixing chamber 204 through the raw material inlet channel 208, and then the raw materials passing through the pre-mixing chamber 204 are stirred by the stirring rod 303 and the stirring blade 304. The upper opening of the flow port 206 is lifted by the interception seat 205 to extend the actual time required for the raw materials to pass through the pre-mixing chamber 204, thereby extending the time for each raw material to be stirred, and then guided into the upper surface of the splashing plate 306 through the drainage port 207.

[0043] Example 2

[0044] On the basis of Example 1, in order to compensate for the excessively fast introduction speed of the raw materials in Example 1, the premixing chamber 204 is filled with raw material liquid, and the newly introduced raw materials flow directly from the top of the raw material liquid into the upper opening of the intercepting seat 205. The stirring time is limited and the stirring is insufficient.

[0045] like Figure 5 As shown, in this embodiment, the feed hopper 1 also includes a discharge port 103, a intercepting groove 102, and a mounting flange 104. The discharge port 103 is inserted and opened at the bottom of the hopper body 101; the intercepting groove 102 is opened at the edge of the upper opening of the discharge port 103; the mounting flange 104 is fixedly sleeved at the lower opening of the discharge port 103; the pre-mixing rod 3 also includes a No. 1 stable frame 305, a splashing plate 306, a beating blade 307 and a No. 2 stable frame 308, and the No. 1 stable frame 305 is fixedly sleeved on the connecting shaft 3 02, the first stabilizing frame 305 is rotatably connected to the inner wall of the flow port 206 through a bearing; the splashing plate 306 is fixedly installed at the lower end of the connecting shaft 302; the number of the striking blades 307 is several, and the striking blades 307 are fixedly installed at the edge of the splashing plate 306 in a ring shape with equal angles; the second stabilizing frame 308 is fixedly installed on the bottom side of the splashing plate 306, and the lower end of the second stabilizing frame 308 is fixedly connected to the inner ring of the bearing 309, and the outer ring of the bearing 309 is fixedly connected to the inner wall of the discharge port 103

[0046] During specific implementation, the splashing plate 306 is driven to rotate by the connecting shaft 302, and the pre-mixed mixed raw materials falling on the upper surface of the splashing plate 306 are splashed out by centrifugal force, causing the raw materials to hit the inner wall of the hopper body 101, and the splashed and spilled raw materials are then dispersed by the various impact blades 307, and finally converge at the intercepting trough 102. As the liquid level in the intercepting trough 102 rises, it is discharged from the discharge port 103, further improving the mixing effect of the raw materials. Before processing each raw material, it is fully pre-mixed during the processing equipment.

[0047] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be encompassed within the present invention. Any reference sign in a claim should not be construed as limiting the claim to which it relates.
